MOTOR.

Patent No. 275,410, dated April 10, 1883.

Application filed January 29, 1883. (No model.)

To all whom it may concern I Be it known that we, BENJAMIN B. POWELL lof Petoskey, Emmet I county, Michigan, have invented a new and usefullmprovementin Spring-Motors, of which the following is thespecification.

Our invention relates to and consists in a combination of aspring-motor, the details of which are hereinafter more fully described.We attain this object by the mechanism-illustrated in the accompanyingdrawings,in which icate corresponding parts in A Figure 1 shows thecomplete motor. Fig. 2 shows the gearing inside of the case; Fig. 3, adetached part of the case in which the spring-wheel and gearing areinclosed. Fig. 4 shows an end view of the bracket. Fig.5 shows thewinding-lever with ratchet-wheel.

A represents a table or support, on which the motor is held by bracketsB. (See Fig. 2.)

C is the case that incloses the spring-wheel and gearing.

D is the spring-wheel.

E is the belt-wheel.

F is a brake and belt wheel.

G is the winding-lever, that has its bearings at a, and when worked upand down on the ratchet-wheel 1) turns the wheel 0 on the hollow shaftH. The wheel I), by means of the ratchet, when the handle end of thelever is raised, turns backward, and when pressed down the spring-pawlbetween the wheel b and a catches and turns the wheel 0, and acatch-spring, d, holds it from turning backward. The wheel 0 being fastonto the hollow shaft H, and the inner end of the flat all the figures.

the spring is wound and held by the wheel 0 and catch-spring d fromunwinding, and the outer end of the said coil-spring is fast onto thespring-wheel D on the inside of the rim at 2. Thus the spring-wheel Dreceives the and by its projecting toothed rim, being engaged with thecogwheel 12, transmits its power to the double wheel f, and the doublecog-wheel f to the double cog-wheel g, and the double cog-wheel g to thepinion k on the shaft 6, and the shaftz' transmits power to theband-wheels E and F,

from which it may be communicated to any device, such as asewing-machine, churn, fan, &c.

A spring-brake, J, is placed on the case'by screws or bolts, and springsagainst one of the band-wheels to govern the motion and to hold themotor from running when not in use. When the motor is wanted to work,the brake is to be pushed aside. Wood is to be used in the brake to rubon the wheel, which, when worn, may be replaced.

K is a brace fastened or bolts, and made hollow shaft H. v

The cog-wheels e, f, or spindles l, case U is together.

at is an arm-brace holding in a bearing the hollow shaft H, the shaft2', and one end of the shaft or pin on which the lever G works. Thelever G- and spring-brake J should project far enough to be convenientto work a stirrup, m, and strap (1 is to be attached to thewinding-lever,as in Fig.5; or a treadle may be substituted.

We do not confine ourselves to the precise form of the details, as theymay be varied without departing from the substance of our invention.

What we claim as new, and desire to secure by Letters Patent, is-

l. The spring-motor composed of the case inolosing theoverhanginggearedspring-wheel, said spring-wheel and the spring winding mechanism beingsecured on the hollow shaft, the transmitting-gear, brake-wheel, andbandwheel on the solid shaft, the latter passing through the hollowshaft, and the spring-brake, all arranged substantially as and for thepurpose set forth.

2. The combination of the solid shaft within the hollow shaft, thelatter having its bearings on the braces n K, substantially asdescribed.

to the case by screws to receive the end of the and g are hung on pinsprojecting from the case 0. The fastened by screws at m to hold itBENJAMIN B. POWELL. JAMES I. ATKINS.
